1. OBJECTIVE To use scientific reasoning, logic, and the nature of science to plan and conduct investigations which will help the students to develop an understanding of force, motion, acceleration, and Newton's law of motion. 2. PERFORMANCE TASKS The student will (a) use and identify dependent and independent variables. (b) use and interpret data from the hands on activities. (c) discuss the relationship between practical and theoretical experiment. (d) construct the practical assignment report based the observation from the hands on activities. (e) use experimental results to make valid conclusions after analysing the data. (f ) investigate and understand Newton's Law of Motion. 3. OVERVIEW Newton's Laws of Motion help us to understand how objects behave when they are standing still when they are moving and when forces act upon them, There are three laws of motion. Here is a description of Newton's Laws of Motion and a summary of what they mean. Inertia - An object tends to resist changes in its motion. Relationship between the mass of an object, the net applied force, and the resulting acceleration - F = m a. Action-reaction pairs - Forces come in pairs. In this lab, you will perform experiments to explore each of the laws of motion 4. MATERIAL / APPARATUS Interactive animations 5. PROCEDURE i.

Discussion: In a few sentences, compare and contrast what you found in the table above for each of the different masses, including any observations you had about how you arrived at the top speed Every simulation run for 30 seconds to compare top speed for each amount of mass. I found that the lesser the masses, the more top speed gains.PART 3- FRICTION Friction Screen Create an applied force to push various objects, and adjust the amount of the amount of friction and see how it affects their motion.

Discussion: (a) Some of the masses would NOT move with a 500N force. Which ones and Why? When friction is maximum, then dustbin (mass 100kg) and fridge (200kg) will not move applied force 500N. Reason is applied force is smaller than the fuctional force acting between blocks and surface, (b) What is the difference between a 500N force and a - 500N force in the simulation? +500 Force in forward force and -500 N is backward force (+ and - represents direction of force) (c) What are some jobs/industries that need to account for things found in this simulation (like applied forces, friction, etc.)?

Discussion: (a) How are mass and acceleration related (if you change one of them, what happens to the other one)? The relationship between mass and acceleration of an object or in this case a car, is given by Newton's second law of motion. According to Newton's second law of motion, the rate at which a body's momentum varies over time is proportional to the force exerted and occurs in the same direction as the force. The above theorem states that the force is proportional to the mass of the object times the acceleration of the object while the mass of the object is held constant. So, we get the formula: F = mxa a = F/m Here, m is the mass of the box and a is the acceleration given to the box. This acceleration is given by a pushing force F. - when force is constant than a x 1/m Acceleration & mass are inversely proportional to each other. When increase in mass than decrease in acceleration & increase in acceleration than decrease in mass.(b) How are Force and mass related (if you change one of them, what happens to the other one)? F = ma acceleration (a) is constant then Fam (force proportional to mass) This means an object with a larger mass needs a stronger force to be moved along at the same acceleration(constant). This is Newton's Second Law of Motion. This means the more mass an object has, the more force you need to accelerate it, and the greater the force, the greater the object's acceleration.(c) How are acceleration and speed related if you change one of them, what happens to the other one)? v = u + at v = final velocity u = Initial velocity a = acceleration t = time Acceleration = change in velocity per second Acceleration and velocity are vectors (so have magnitude and direction) Velocity vector = speed + direction Acceleration vector = change in speed per second + direction . An object will be increasing in speed so long as it's acceleration is positive. Since it is possible for an acceleration to be both positive and decreasing, it is possible that an object can be both increasing in speed and decreasing in acceleration. Explanation: - U a(acceleration) t (constant at y(final velocity) (initial velocity) time) v= u+ at u = constant = t= 5 10 10 5 20 30 10 5 10 20 In this case a decrease & positive so speed also decrease 10 15 25 10 -5 UI -15 25
